Ka’b bin Maalik (ra) related his account when he lagged behind in the Battle of Tabook. He said:
When Allah accepted my repentance and the Messenger of Allah (ﷺ) announced at the time of the fajr prayers that Allah had accepted my repentance, people met me in large number and congratulated me on the acceptance of my repentance. They said, "Congratulations to you. Allah has approved your repentance." And I entered the Masjid Nabawi. People were sitting around him. Talhah bin Ubayd Allah ran towards me after standing up and shook hands with me and congratulated me. By Allah, one of the Muhajirs besides him stood up for me. I will not forget this demonstration of Thalhah’s.

حَدَّثَنَا عَبْدُ اللهِ بْنُ صَالِحٍ قَالَ: حَدَّثَنِي اللَّيْثُ قَالَ: حَدَّثَنِي عُقَيْلٌ، عَنِ ابْنِ شِهَابٍ قَالَ: أَخْبَرَنِي عَبْدُ الرَّحْمَنِ بْنُ عَبْدِ اللهِ بْنِ كَعْبِ بْنِ مَالِكٍ، أَنَّ عَبْدَ اللهِ بْنَ كَعْبٍ، وَكَانَ قَائِدَ كَعْبٍ مِنْ بَنِيهِ حِينَ عَمِيَ، قَالَ: سَمِعْتُ كَعْبَ بْنَ مَالِكٍ يُحَدِّثُ حَدِيثَهُ حِينَ تَخَلَّفَ عَنْ رَسُولِ اللهِ ﷺ عَنْ غَزْوَةِ تَبُوكَ، فَتَابَ اللَّهُ عَلَيْهِ: وَآذَنَ رَسُولُ اللهِ ﷺ بِتَوْبَةِ اللهِ عَلَيْنَا حِينَ صَلَّى صَلاَةَ الْفَجْرَ، فَتَلَقَّانِي النَّاسُ فَوْجًا فَوْجًا، يُهَنُّونِي بِالتَّوْبَةِ يَقُولُونَ: لِتَهْنِكَ تَوْبَةُ اللهِ عَلَيْكَ، حَتَّى دَخَلْتُ الْمَسْجِدَ، فَإِذَا بِرَسُولِ اللهِ ﷺ حَوْلَهُ النَّاسُ، فَقَامَ إِلَيَّ طَلْحَةُ بْنُ عُبَيْدِ اللهِ يُهَرْوِلُ، حَتَّى صَافَحَنِي وَهَنَّانِي، وَاللَّهِ مَا قَامَ إِلَيَّ رَجُلٌ مِنَ الْمُهَاجِرِينَ غَيْرُهُ، لا أَنْسَاهَا لِطَلْحَةَ.
